Warning Triangle Sign Size
Road signs are very important to maintain the safety of motorists. 
They serve as early warning for upcoming threats on the road, which may possibly lead to traffic accidents. With their help, drivers can easily make adjustments in order to avoid such tragedies from happening. Aside from signs like ‘animals crossing,’ ‘construction ahead’ and ‘dangerous curve ahead,’ another highly important symbol used on the road is the warning triangle sign.
The Size of a Warning Triangle Sign
For every side of a warning triangle sign, the standard length is 43 centimeters. Additionally, each side is 3.7 centimeters wide and 0.5 centimeter thick. It usually comes in pairs, one of which is red while the other one is yellow. The primary purpose of this early warning device is to alert upcoming motorists of the possible danger that lies ahead. It is commonly used when changing tires, checking for engine troubles and in case of vehicular accidents. It clears the traffic away while the problem is being solved. With the help of this sign, upcoming vehicles can slow down and avoid bumping right into the stalled vehicle ahead.
